Results from Sleipner gravity monitoring: Updated density and temperature distribution of the CO2 plume
Abstract To help monitor the evolution of stored CO 2 , we have made precision seafloor gravity measurements at 30 seafloor stations above the Sleipner CO 2 plume in the years 2002, 2005 and 2009.Expand

Vertical deformation monitoring at Axial Seamount since its 1998 eruption using deep-sea pressure sensors
Pressure measurements made on the seafloor at depths between 1500 and 1700 m at Axial Seamount, an active submarine volcano on the Juan de Fuca Ridge in the northeast Pacific Ocean, show evidenceExpand

A Self-Calibrating Pressure Recorder for Detecting Seafloor Height Change
One method to detect vertical crustal deformation of the seafloor, where Global Positioning System (GPS) surveys are not possible, is to monitor changes in the ambient seawater pressure, whose valueExpand

An ocean bottom gravity study of the southern Juan de Fuca Ridge
We use seafloor and sea surface gravity data to model density structure along the southern Juan de Fuca Ridge. We determine the average density of the shallow oceanic crust at the ridge usingExpand

Deep-towed gravity surveys in the southern California Continental Borderland
We surveyed two sites in the southern California continental borderland with a newly developed instrument, a towed deep ocean gravimeter—a gravity sensor that can be towed a few tens of meters aboveExpand

Resolving quadrature fringes in real time.
In many interferometers, two fringe signals can be generated in quadrature. The relative phase of the two fringe signals depends on whether the optical path length is increasing or decreasing. AExpand
